In September 2014 Strati, an EV with a 3D printed body was printed in 44 hours, then assembled and tested in 3 days. The Strati was the winning design of a competition hosted by Local Motors, and was collaboratively manufactured with Oak Ridge National Labs and Cincinnati Incorporated. Strati is the first car to have its chassis and body printed in one solid piece. Local Motors’ Strati – 3d Printed EV body In the link above Business Insider did interviews with Local Motors, and Cincinnati Incorporated on the design and manufacturing of the Strati. The video discusses how 3D printing (additive manufacturing) creates a more streamlined design process because it allows for rapid prototyping. This means that prototypes can be fabricated quickly because there doesn’t need to be specific tooling for each new design. The video also discusses why additive manufacturing is far from replacing traditional auto manufacturing. Although Ford has been using the technology for over 25 years, additive manufacturing is unlikely to be implemented in the construction of combustion engine cars anytime soon. This is because they traditional cars have many more parts and much more complex requirements than EVs do. Since EVs have fewer parts, they have more potential to be manufactured in experimental ways.
